<span>JobKOctets类是一个整数值打印属性类，用于指定以K个八位字节为单位的文档的总大小，即以作业中请求处理的1024个八位字节为单位。</span>
<span>值必须向上舍入，所以1到1024个八位字节之间的作业必须表示为1K个八位字节，1025到2048必须是2K字节等。对于多点打印作业（具有多个文档的作业），JobKOctets值通过将单个文档的大小以八位字节相加，然后舍入到下一个K个八位字节值来计算。</span>
<p> <span>JobKOctets属性描述作业的大小。</span> <span>这个属性不是一个计数器;</span> <span>如果已知的话，它是有用的路由和调度信息。</span> <span>如果打印请求中未提供JobKOctets属性的值，打印机可能会尝试计算。</span> <span>即使客户端确实为打印请求中的JobKOctets属性提供了一个值，如果打印机能够计算比客户端提供的值更准确的值，打印机也可以选择更改该值。</span> <span>打印机可能能够在作业提交时间或任何稍后的时间点确定JobKOctets属性的正确值。</span> </p>
<p> <span>JobKOctets值不能包括由<code>Copies</code>属性指定的份数所<a href="../../../../javax/print/attribute/standard/Copies.html" title="javax.print.attribute.standard中的类">贡献的</a>乘数，而不管设备是否可以处理多个副本，而不会在作业或文档数据上进行多次传递，而与输出是否整合不一样。</span> <span>因此，该值与实现无关，并且指示与K个八位字节中独立于副本数量测量的文档的大小。</span> </p>
<p> <span>JobKOctets值也不得包含乘法因子，因为嵌入在文档数据中的拷贝指令。</span> <span>如果文档数据实际上包含文档数据的复制，则此值将包括此类复制。</span> <span>换句话说，此值始终是源文档数据的大小，而不是要生成的硬拷贝输出的度量。</span> </p>
<p> <span>一个文档的尺寸的计算基于由文档的指定的打印数据表示类<a href="../../../../javax/print/DocFlavor.html" title="javax.print中的类"><code>DocFlavor</code></a> ，如示于下表中。</span> </p>

<p> <span>*在这些情况下，打印服务本身会生成发送到打印机的打印数据。</span> <span>如果打印服务支持JobKOctets属性，对于这些情况，打印服务本身必须计算打印数据的大小，替换客户指定的任何JobKOctets值。</span> </p>
